Reconditioning tracks on asphalt pavement by using thin paste mixture of modified emulsified asphalt and construction method thereof

Abstract

This is a kind of restoring the tracks of the bitumen road surface with the modified emulsified bitumen watery slurry mixed materials and its job practice. Spread single layer modified emulsified bitumen watery slurry mixed materials on the bitumen road surface of 10 - 20 mm depth, and spread double layer modified emulsified bitumen watery slurry mixed materials on the bitumen road surface of 20 - 40 mm depth. The job practice of single layer modified emulsified bitumen watery slurry mixed materials is: close down the traffic, process the original road surface, lay samples, spread, appearance control, joint slots, initial maintenance and quality inspection. Other building steps of the lower layer job practice of the double layer modified emulsified bitumen watery slurry mixed materials are the same as that of single layer, except that the allocated proportion of the single layer modified emulsified bitumen watery slurry mixed materials is different and without quality inspection. The upper layer building steps are: spread, initial maintenance and quality inspection. It has such advantages as high abrading-resistant performance, thin structure layer, long using life, high building speed, fast molding, short building period, fast traffic opening, long building season, low resource waste, no deleterious gas euduction and so on.

Description

technical field [0001] The invention belongs to the technical field of coagulating pavement paved on site for roads or airports, in particular to a pavement paved on site with several layers of different materials. Background technique [0002] With the rapid development of my country's economic construction, the construction of high-grade highways is also changing with each passing day. In 1985, starting from the construction of a first-class highway, in 1988, my country's first expressway, the Hujia Expressway, was completed and opened to traffic, and in 1990, the Shenyang-Dalian Expressway was opened to traffic. Over the next ten years, the development of my country's high-grade highways has grown linearly. So far, the mileage of highways in my country has been close to 35,000 kilometers, and the high-grade highways have exceeded 300,000 kilometers. The development momentum is very strong, but the maintenance work of high-grade highways is relatively lagging behind. At ...

Problems solved by technology

The main disadvantages of these two kinds of repairing ruts are: the cutting grooves milled at the ruts of the asphalt pavement are wide and deep, the amount of materials used is large, the cost is high, there are many supporting equipment, the process is complicated, the progress is slow, the environment is polluted, and the operation is difficult. , difficult to control, long initial maintenance time, affecting traffic, etc.
